"WebNov 3, 2024 · 5. A periodic continuous-time signal satisfies x ( t) = x ( t + T 0) for all t. The period T 0 doesn't need to be a rational number. A periodic discrete-time signal satisfies x [ n] = x [ n + N] for all integers n. The period N is an integer. If you sample a periodic continuous-time signal, you don't necessarily get a periodic sequence. " - Periodicity of a signal
